General Information:
CMAX brand Silica bricks are made from high quality quartz tail sand, lime and mineralizing agent through the process of crashing, screening, mixing, pressing, drying and sintering.
Features of Refractory silica bricks for Glass Kiln:
1. high volume density of 2.34 g/cm3
2. high SiO2 content of 96%
3. low iron content of 0.8%
4. low melting point of 5%
Applications of Refractory silica bricks for Glass Kiln:
Because of the high temperature resistant performance significantly, long service life characteristics (as long as more than eight years) of refractory silica brick for Glass Kiln, it can significantly improve the quality of glass, so the refractory silica bricks are widely used in all kinds of glass furnace melting department, regenerator and other important parts.

- Q: How to divide the fire resistant level of EVB?
- Inorganic materials: Level A incombustible material is mainly divided into three levels, which attributed to two types of materials! Inorganic materials: Rock wool, foam cement, vitrified micro bead, foam glass organic: Eps xps polyurethane phenolic aldehyde, polystyrene particles are divided into two manufacturing techniques including field fabrication and pre-production polyurethane - now sprayed, precast slab eps, xps, phenol - now posted, precast slab (composite board)
- Q: What is acid refractory material?
- Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, there are refractories for special occasions. Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 93% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, low thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used. Neutral refractory is mainly composed of alumina, chromium oxide or carbon.
- Q: Does the production of refractory belong to advanced technology？
- Refractory is traditional ceramic material. We can only say that national development is relatively backward. If the refractory is counted as new material, then it still has huge development potential.
- Q: What's the refractory material?
- Main components of basic refractory are magnesium oxide and calcium oxide, and magnesia brick is commonly used. For the magnesia brick with magnesium oxide content of more than 80%-85%, it has good resistance to basic slag and scum, and it has higher refractoriness than that of the clay brick and silica?brick. It is mainly applied to the open hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting equipment and some high-temperature devices.
- Q: How to count the construction costs of refractories?
- In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric?acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.
- Q: I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
- What you said is the pixel! Only that has b1b2. Level b1 is the fireproofing level b1, because the particle does not belong to the fireproofing material. Only can fire?retardant. The wholesale of all kinds of thermal insulation material and construction need to look at the name.
- Q: What refractories are resistant to fluorine gas?
- It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica?brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
- Q: Which kind of refractory floor is easy to use? ?
- Since it is used in public places, fireproofing is quite important.
- Q: What are the main characteristics of the sic refractories?
- 1. The usge temperature of silicon carbide refractory is generally 1760 ℃ 2. The silicon carbide refractories can withstand the dramatic changes of temperature and have a good thermal shock resistance performance. To prevent the cracking or breaking of lining refractories. 3. Under the conditions of high or low temperature, it can withstand a certain compressive stress. 4. Under the conditions of high or low temperature, it can withstand friction. 5. It can withstand the huge hydraulic pressure or buoyancy of the metal. 6. It can also withstand the effect of furnace gases to prevent the infiltration of other refractories and reactions.
- Q: what's the materials of fireproof?housing?
- I'm very glad to answer for you. 1. Mobile homes in high-rise buildings, as for the interior hidden artifacts of single and multi-layer mobile homes, when its fire endurance is ruled above 1.5 h, you should choose the non-swelling large activity fire?retardant?coating; 2.as for Indoor mobile house, light roof mobile house and mobile house need to be decorated, when its fireproof limit is ruled under 1.5 h, you can choose swelling mobile house fire?retardant?coating; 3. The fire endurance of mobile houses need to be above 1.5 h, outdoor mobile houses project shoule better not choose swelling fire?retardant?coating. 4. Indoor mobile houses extremly need to be decorated, hot standby is a living place of mobile houses, bearing steel structure of equipment, bracket, the part easy to be knocked like skirt, its fire endurance needs to be above 1.5 h, you better choose fireproof?panel of mobile houses. 5. Open mobile houses, you should choose fire?retardant?coating of mobile houses suitable for outdoor, and use the coating with over one-year outdoor mobile houses project operation and the coating function without significant changes. 6. multiple layer coating should be matched with each other, the bottom layer coating should be able to be used with rust-proof paint together or have rust-proof function. 7, while choosing the fire?retardant?coating for special function, it should have over one-year project operation and verification case and matched fire-proof function.
